Added support for libICU for collation and toLower/toUpper.

This patch uses icu to do string collation via QString::localeAwareCompare
function and for QString::toLower/toUpper - which is important e.g. for turkish
locales where uppercased 'i' is not a latin 'I'.

Based on the patch by Harald Fernengel
